Which types of information does the Attitude and Heading Reference System provide?

The Attitude and Heading Reference System (AHRS) is designed to provide critical information about the aircraft's orientation in space. Specifically, it delivers data on roll, pitch, yaw, and magnetic heading.

Roll refers to the rotation of the aircraft around its longitudinal axis, which is essential for understanding how the wings are oriented concerning the horizon. Pitch indicates the angle between the aircraft's nose and the horizon, crucial for controlling climb and descent. Yaw describes the rotation around the vertical axis, important for direction changes. Magnetic heading provides the compass direction in which the aircraft is pointed, which is vital for navigation.

This comprehensive set of orientation data is crucial for pilots to maintain control of the aircraft and to ensure safe navigation. The other options present various types of data that, while significant in aviation, are not functions of the AHRS. For instance, speed and altitude are typically provided by different systems such as the airspeed indicator and altimeter, while heading and distance could involve navigation systems rather than the core functions of the AHRS.
